Characterization of regional diastolic pressure gradients in the right ventricle.
Regional intraventricular pressure gradients exist in the left ventricle (LV) during both the early and late filling phases of diastole. These regional pressure gradients comprise a fundamental component of the mechanism of normal LV filling. To determine whether similar diastolic pressure gradients also occur in the right ventricle (RV), we measured right atrial (RA) and RV regional pressures ...

متن کاملNegative diastolic pressure in the intact canine right ventricle. Evidence of diastolic suction.
To determine whether the canine right ventricle (RV) can develop a negative diastolic pressure indicative of suction, RV pressure was measured in 15 dogs, with catheter-tip micromanometers. Six dogs were studied only with the chest closed. In these dogs, intrapleural pressure was measured medially (near the heart) in four and laterally in two. In nine dogs, RV pressure was evaluated with the ch...
متن کاملThe Impact of Cardiac Rehabilitation on Pulmonary Artery Systolic Pressure and Left Ventricular End-Diastolic Pressure in Patients after Coronary Artery Bypass Graft Surgery
Background:Cardiac rehabilitation program (CRP) is a useful method of modifying cardiovascular risk factors, improving life expectancy and quality of life in patients with ischemic heart disease (IHD). The present study was conducted to evaluate the effects of cardiac rehabilitation on the pulmonary artery systolic pressure (PASP) and left ventricular end-diastolic pressure (LV...
متن کاملAcute displacement of the diastolic pressure-volume curve of the left ventricle: role of the pericardium and the right ventricle.
IN CHRONIC CARDIAC DISEASE, the left ventricular diastolic pressure does not provide a reliable guide to the diastolic left ventricular volume,' and measurement of chamber volume, shape and wall thickness are necessary to identify changes in the myocardial stress-strain relation.' Under acute conditions, the stiffness of the left ventricular chamber progressively increases as passive diastolic ...
